Tag: Goodhart’s law

With the Conservatives and Liberal Democrats now in power in the UK and with the Labour Party, having lost the election, being now in the midst of a leadership campaign, politicians from across the political spectrum are balming Gordon Brown for the ‘mess the country’s in’. The UK has a record budget deficit and debt, and is just emerging from a deep recession, when only a few years ago, Gordon Brown was claiming the end of boom and bust. But is the condition of the UK economy Mr Brown’s fault? Would it have been any better if others had been in charge, or if there had been even greater independence for the Bank of England of if there had been an Office of Budget Responsibility (see)?

The following podcast by Martin Wolf, chief economics commentator of the Financial Times, considers this question. He argues that:

Everybody would like to blame Gordon Brown for the financial crisis. But he was only acting in line with the national consensus on economic policy.

Questions

  1. Explain what is meant by ‘the great moderation’.
  2. Should regulation of the banks be handed back to the Bank of England?
  3. Why may controlling inflation not necessarily result in stable economic growth? Is this a case of Goodhart’s Law?
  4. Why was the UK economy especially fragile during the banking crisis and its aftermath?
  5. What, according to Martin Wolf, was Mr Brown’s biggest mistake?
  6. Could a mistake be now being made by following the conventional wisdom that cutting the deficit is the solution to achieving sustained recovery?

The following article by Will Hutton looks at the relative efficiency of private- and public-sector organisations. The public sector is typically characterised as inefficient and providing a poorer level of service and poorer quality products than the private sector. After all, the private sector is driven by the profit motive, where providing a good service would seem to be a key ingredient in making more profit.

Yet when you look around you, this portrayal can be seen as far too simplistic. On the one hand, much of the public sector has been forced to be efficient, following many years of tight budgets. At the same time, many in the public sector are keen to deliver a good service, not only because that is required by their employers, but because they are motivated by a sense of public duty and professionalism. On the other hand, there are many market failings in large parts of the private sector, where monopoly power, asymmetric information and externalities are rife. Read the article and see if you agree with Will Hutton’s analysis.

Questions

  1. What are the incentives to encourage either private-sector companies or public-sector organisations (a) to be efficient in the sense of cutting out waste (X-efficiency); (b) to be allocatively efficient; and (c) to provide a high quality of service to customers / clients / patients / students, etc.?
  2. What market failures may prevent private-sector companies from achieving (a) to (c) above?
  3. What organisational failures may prevent public-sector organisations from achieving (a) to (c) above?
  4. How is Goodhart’s Law relevant to the setting of performance targets in both the private and public sectors?

In a speech to Scottish business organisations, Mervyn King, the Governor of the Bank of England, argued that it might be necessary to split banks up. The aim would be to separate the core retail banking business, of receving deposits and lending to individuals and businesses, from the more risky and exotic wholesale acitivites of banks, such as securitisation, speculation and hedging – so-called ‘casino banking’.

Governments around the world, as represented at the G20 meeting at Pittsburg in September, have favoured tougher regulation of banks. But Mervyn King believes that this is not enough. It may not prevent the reckless behaviour that resulted in the credit crunch and bank bailouts by the government. “Never has so much money been owed by so few to so many. And, one might add, so far with little real reform.” And if regulation were to fail and banks were to get into difficulties, what would happen? There would have to be another bailout. As Mervyn King said, “The belief that appropriate regulation can ensure that speculative activities do not result in failures is a delusion.”

There are two key problems.

The first is Goodhart’s Law. If rules are set for bank behaviour, banks may adhere to the letter of the rules, but find ways around them to continue behaving in risky ways. The rules may cease to be a good measure of prudent behaviour.

The second is moral hazard. If banks know that they will be bailed out if they get into difficulties because they are too big to fail, then this encourages them to take the risks. As Mervyn King said in his speech, “The massive support extended to the banking sector around the world, while necessary to avert economic disaster, has created possibly the biggest moral hazard in history. The ‘too important to fail’ problem is too important to ignore.”

So should the banks be split? Is there any likelihood that they will? Or are Mervyn King’s proposals merely another headache for the government? The following articles looks at the issues. The first link below is to his speech.

Questions

  1. Explain what is meant by ‘moral hazard’ in the context of bank bailouts. Are the any ways in which banks could be prevented from failing during a crisis without creating a moral hazard?
  2. Does regulation necessarily involve Goodhart’s Law? To what extent is it possible to devise regulation and avoid Goodnart’s Law?
  3. What are the arguments for and against splitting banks’ core business from more risky ‘casino banking’?
  4. Does the separation of retail and investment banking necessarily involve splitting banks into separate organisations? If they are not split, how can the government or central bank underwrite retail banking without underwriting riskier investment banking?
